Hi,

 I've been told you are the maintainer of the an-driver,
hence, this email.
 I recently upgraded the firmware and on my Cisco 340-
series aironet PC-card and the driver failed to initialize,
complaining about record size mismatch:

an0 at pcmcia1 function 0 "Cisco Systems, 340 Series Wireless LAN Adapter"an0: R
ID 0xff10 record length mismatch -- expected 156, got 158
: read record failed

 So, I started padding the data structures and, lo and behold
it worked. Though, the last data structure in anvar.h I patched
need 748 bytes padding which seemed pretty bizarre. Anyway,
I've got a patch for this if you want it. It's been working pretty
well for me. I'll include dmesg and ancontrol -I output as well.

Cheers,
Jon

After updating the firmware on my Cisco 340-series aironet PC-card,
the driver failed to initialize. Here's a hack that makes
the driver start at least. It feels really weird that
we need to pad one structure with 748 bytes...
